The MOTM-650 is a 2U wide, full-featured 4-channel MIDI-CV converter. The MOTM-650 packs all these features into a 2U wide module, using the latest SMT data converters, low-drift op amps and precision voltage references. Most MIDI-CV converters use 12-bit DACs: the MOTM-650 uses a true 16-bit DAC, and an octal 10-bit DAC for the Velocity/Aux outputs.

Features include:

--Voice allocations settable as four 1 voice, two 2 voice, or one 4 voice group - each voice group separately addressable via MIDI --Voice assignment modes on a per voice configuration: Poly 1, Poly 1 steal, Poly 2, Poly 2 steal, Unison, Solo Unison, Solo, Solo Rotate. --Dual arpeggiators, each arpeggiator assignable to any active voice group - one arpeggiator per voice group --Arpeggiator clock sources - MIDI IN Clock, internal clock (60-238BPM weighted), or external --Arpeggiator clock divisors /4, /3, /2, /1.5, 1X, 1.5X, 2X and 4X the clock rate --Arpeggiator note order as up, down, up/down, and down/up --Arpeggiator modes are normal, ordered, ping pong, and random --Portamento - per voice group configurable as constant rate or constant time --Each voice group is independently configurable --Firmware updateable via MIDI (Windows and Mac OS 9 update utilities provided) --All MOTM-650 options settable via MIDI CCs or MIDI System Exclusive commands as well as the front panel user interface --MOTM-650 Settings and state are remembered across power cycles --Patch storage for MOTM-650 settings (up to 32) - recallable via MIDI patch change command --Microtuning per MIDI spec --Pitch bend adjustable from +/- 0 to 24 to be added to note CV on all voices --Each of 4 AUX outputs assignable to pitch bend, channel aftertouch, or any MIDI CC. --Velocity jack on each voice can be configured to be velocity or a trigger - providing a 5ms pulse when the voice is retriggered --LEDs to monitor MIDI IN activity, internal/external/MIDI clock, and voice gate operation --8X2 LCD with variable backlight and 4 buttons for the user interface --External clock in jack --Transmits MIDI clock if set to external or internal clock

NOTE: This module requires a MOTM-950 or other source of +5V, 575ma power
